New equation of a wheeled vehicle moving

Mamiti G.I.


Conclusions of generally accepted and recently proposed equations of wheeled vehicle (car, tractor, motorcycle and other) motion are given. It is shown that a necessary condition for correctness of equation of motion is to reduce forces and moments acting on a vehicle to contact of driven wheels with road.

Diagnostics of resource structural parameters of geared transmissions

Dobrolyubov I.P.


Identification method for diagnostics of resource structural parameters of gearing of transmissions and reducers of agricultural machinery is suggested. The method is based on analysis of deformation of distribution density and correlation function of amplitudes of vibroacoustic impulses or impulses of shaft angular velocity on exceedance by mean value or by dispersion (following along with tooth changeover periods) of level corresponding to occurrence of defects and critical operating mode. Application of this method is investigated.
